title: Diagnosis and treatment of cornual obstruction using a flexible tip guidewire.
abstract: Proximal tubal obstruction, either unilateral or bilateral, is a frequent finding on hysterosalpingogram (HSG). Approximately two-thirds of the fallopian tubes resected for proximal tubal obstruction reveal an absence of luminal occlusion. The distinction between true pathologic occlusion and either spasm or plugging is crucial in determining therapy. We combined hysteroscopic cannulation of the proximal fallopian tube with laparoscopy in 11 patients with proximal tubal obstruction diagnosed by HSG and confirmed at laparoscopy. Hysteroscopic cannulation was able to be performed in 72% of the fallopian tubes attempted, and there was a postcannulation patency rate by HSG of 73%. Six of the 11 patients became pregnant after tubal cannulation and adjunctive distal tubal surgery. Hysteroscopic cannulation of the fallopian tube is a safe diagnostic procedure that can be used to identify those patients with true proximal occlusion, and may also serve as a therapeutic procedure in some of these patients.
